'Scott the Dick' characters in TV

Scott The Dick is a character who first appeared in the Terence & Philip episode. He is every TV bad guy: He's arbitrarily nasty for no reason, and exists solely to make life difficult for the protagonists. He is an easy formula for lazy one dimensional villains.

The biggest Star Trek example of a 'Scott The Dick' is Brunt, but DS9 and some of the other Treks are rife with them, especially when it comes to single-appearance villains. Other recent examples are:

Jamm from Parks & Recreation
Eckley from CSI

What are some other big Scott the Dick characters in TV, and why do screenwriters fall back on them so easily? Is it just more economical to have one composite character for everybody who gets in the way of the characters getting what they want?

As for why? As part of the storytelling process, there usually needs to be conflict. TV is a business. Therefore, it has to be created with a certain economy. The dick character creates conflict with economy.

^ I didn't see Q as a "Scott the Dick" kind of character. Sure, he was a pain, but I did find some depth in him. Especially in episodes like "Death Wish" and even "Q and the Grey". About the only time I saw him as a "Scott" was on DS9...

Oh I completely agree -there's tons of depth to Q, marvelously portrayed by de Lancie, but he's also a colossal jerk to Picard, Riker, et al in each of his appearances. Whether you (the general "you") qualify that because he's a demi-god or because he's a Scott Dick kind of person is entirely subjective.

Naw man. Naw.
All of those characters are/were antagonists on some level, sure, but that antagonism makes perfect sense in the context of their characters. Pierce devolved into just being the dick character for a while, certainly, but Lucille was a different trope all together and Dwight always had some method to his madness and was rarely out to do anyone harm. Cordelia was set up to play to the bitchy "queen bee" archetype in order to break it, but even then she had moments of good intent and sympathy even in the first season when she was barely a character.
